Answer:
length = 11 yard
width = 5 yard
Step-by-step explanation:
Area of a rectangle = L W
where A = 55 yard
L = 3W - 4
find: Length
width
solution:
A = L W
55 = (3W - 4) W
55 = 3W² - 4W
3W² - 4W - 55 = 0
use quadratic equation to solve for W:
W = <u> - (-4) ± √(-4)² - 4(3)-55 </u>
2(3)
W = 5, W = -11/3
substitute W=5 to equation L = 3W - 4 to solve for L
L = 3W - 4
L = 3(5) - 4
L = 15 - 4
L = 11
therefore, the dimensions of a rectangle:
length = 11 yard
width = 5 yard
GCF of 12,18 = 6
LCM of 12,18 = 36
Answer:
true
Step-by-step explanation:
3/12 can be made into 1/4. 3/3=1 and 12/3=4. 1/4 is correct.
Answer:
Step-by-step explanation:
2.17 * 10-2 = 2.17 * 1/(10^2) = 2.17 / 100 = 0.0217
4.18 * 10^-4 = 4.18 * 1 / (10^4) = 4.18 / 10000 = 0.000418
3.26 x 10^-3 = 3.16 * 1 / (10^3) = 3.16 / 1000 = 0.00316
least to greatest is :
(1) 4.18 * 10^-4
(2) 3.26 * 10^-3
(3) 2.17 * 10^-2
